Upgrades Plugin Error: "doesn't look like an ERC 1967 proxy with a logic contract address"

Hello, I am deploying an upgradeable contract with the upgrades plugin and keep getting this error

Error: Contract at 0xdeaBbBe620EDF275F06E75E8fab18183389d606F doesn't look like an ERC 1967 proxy with a logic contract address

This is my code:

describe("LCV2", () => {
    it("Upgrades to v2", async () => {

        const LCV2Mock = await hre.ethers.getContractFactory("LCV2Mock");

        const lCV2Mock = <LCV2Mock>(await hre.upgrades.upgradeProxy("0xdeaBbBe620EDF275F06E75E8fab18183389d606F", LCV2Mock));
        expect (await lCV2Mock.version()).to.equal("This is LC V2!");
    });
})

I am getting the proxy address from the network file:

 "b10bc8a5180c13e4efa1aa2f8f6bf857af0142cdc5f3b50830e983900a2304de": {
      "address": "0xdeaBbBe620EDF275F06E75E8fab18183389d606F",
      "txHash": "0xce69f75f4e6923ea8cee20ccc07aa5a9b9d3444af1e5e74d3663f51d0330019d",
      "layout": {

I have implemented this before successfully.
Not sure what I am missing today..

That seems like an implementation address (from the impls section of the network file). You should look for the proxy address (see the proxies section of the network file instead).

Hi!
I have a something look like a same issue but...

My proxies is

  "proxies": [
    {
      "address": "0x74a7D431499bE64f2e3C4Dd47e59387d2B8BB969",
      "txHash": "0x1e32967f1a5768c86656478a7c158f0d264ffe2c5556e9d6901b67e423a53b57",
      "kind": "transparent"
    }
  ],

Deploy script

const TransparentUpgradeableProxy =
  "0x74a7D431499bE64f2e3C4Dd47e59387d2B8BB969";

async function main() {
  console.log("Started UPG deploying ... ");
  const ERC721 = await ethers.getContractFactory("ERC721");
  await upgrades.upgradeProxy(TransparentUpgradeableProxy, ERC721);

  console.log("Upgraded ... ");
}

As a result I get an error

Error: Contract at 0x74a7D431499bE64f2e3C4Dd47e59387d2B8BB969 doesn't look like an ERC 1967 proxy with a logic contract address

@liscody Can you check that you are using the correct network and that the address actually has the proxy contract deployed on that network?

im getting the same issue with:
"@openzeppelin/hardhat-upgrades": "^2.4.1" and
"@openzeppelin/contracts": "^5.0.0",
"@openzeppelin/contracts-upgradeable": "^5.0.0",

i already migrated to the the most recent deps for ethers, hardhat and openzeppelin upgrades,

i get this error message when trying to retrieve the implementation address with:

upgrades.erc1967.getImplementationAddress

error:
Error: Contract at 0x971b64614c21CAD5b7B77789509F33F129a856DF doesn't look like an ERC 1967 proxy with a logic contract address

i think your error is choosing the kind: 'transparent' as option if your erc196 i think is uups

@RasenGUY In your script, did you ensure that you are waiting for the proxy to be deployed before running getImplementationAddress? If you still have the issue, please provide the information listed under Required information when requesting support for Upgrades Plugins so that we can take a closer look.

you are right @ericglau, after waiting for the deployment everything works like a charm,
so fo others:

const deployedContract = await upgrades.deployProxy(contractFactory, [initializerparams], opts);
await deployedContract.waitForDeployment();

it was written in the docs but i missed it during migration.
